2021, Hanzhong Agricultural University team announced that
found the fish bone gene
is expected to achieve the news that eating fish is not picky about thorns
attracted attention on the Internet
September 27
Aquatic Products College of Huazhong Agricultural University released the latest news
The Gao Zexia team of the school
breeding
that has no intermuscular stings at all
Wuchang Fish ( trench trench ) seedlings
is expected to be promoted on a large scale!
Since this year, they have used the first generation of hybrid (F0 generation) stingfish that have been obtained, and bred Wuchang fish (Group Head Bream) seedlings (F1 generation) without intermuscular spines (F1 generation)
will be further carried out next year. According to normal procedures, after the new germplasm traits are stabilized, they can obtain relevant national certification and can be promoted on a large scale.
directly look at the comparison picture
From the picture displayed, you can see that there is almost no difference in appearance compared to a thornless Wuchang fish weighing 51.1 grams and a thorny Wuchang fish of the same length.
In X-ray, they can be seen with obvious differences. There are rows of small thorns growing horizontally in the body of the thorny Wuchang fish, shiny in the light, and shadows in the body of the thorny Wuchang fish, which are completely invisible.
bone staining diagram clearly shows the comparison of the number of fish bones. The skeletons of Wuchang fish with thorns and interstitial thorns appear dense, while the skeletons of Wuchang fish without thorns are relaxed and there are no extra small thorns.
Gao Zexia said that the thornless Wuchang fish they bred this year are growing well, and more testing is currently underway.
It is reported that the stingless fish is not only implemented on Wuchang fish, but some experts also reported the experiments and applications of different fish after they introduced the stingless main effect gene found by Gao Zexia's team. After the previous tests of knocking out the main effect gene that regulates the growth of fish bones in grass carp and silver carp , the latest gene knockout was achieved on silver carp , and the F0 generation of stingless fish was obtained, with a reduction of 50% in the intermuscular spines. According to the current R&D speed, it is expected that we will be able to eat prickly fish in the near future. Netizens in the comment section of
have a bolder idea:
Are you looking forward to it?
